subject: Learn from This Toshiba L25-S1195 AC Adapter [print this page] Now the power adapter has adopted extensive SMD components. Once the device has certain problem with the SMD components, it's difficult to repair it by yourself. I had some experiences of laptop AC adapter's maintenance, such as Toshiba L25-S1195 AC adapter, HP Dv6190eu AC adapter, and Compaq V2606au AC adapter and so on.
The capacity of the ac adapter increases day by day. At the same time, the test to the SMD component raised. If the AC adapter use some low quality materials, that must be very dangerous. It's easy to have troubles. Take this Toshiba L25-S1195 AC adapterfor example, I will list some instructions that one should follow.
1. Be careful when you winding the power cords. Usually we wind it with random. That is forbidden. Most AC adapters are damaged by the broken wire. That is why this Toshiba L25-S1195 AC adapter came into the service center, for the formation of internal cable circuit got broken. If you are question about the wire, test with a multimeter to identify the power cord, so as to simplify the maintenance of the difficulty. Do not start trying to open the adapter covering. It's expert's job to unfold the adapter case. Once you open it, your AC adapter will never turn back as it used to be.
2. If the original adapter failed to work. And you can not repair it right away. You can use other adapter as long as the output voltage can power roughly the same. Laptop internal regulator circuit also propped up, not too worried about the output voltage mismatch.
3. Once heard that the broken adapter burned computer motherboard. I think that is joking. Or at least, there are something wrong with the internal circuit regulator had some problems. The motherboard can't be ruined by AC adapter.
4. Do not damage the shell. Shell damage, the electromagnetic radiation appears to enhance and so on, affect the stability of the machine. If the shell damage, repair as much as possible.
If you AC adapter have some abnormal change, remove it from the power charger. It's dangerous to use it. Or a new replacement is a better choice. As this new Toshiba L25-S1195 AC adapter, this new replacement is really a nice prodct.
